A train travels a distance of 480 km at a uniform speed. if the speed had been 8 km/h less. then it would have taken 3 hours more to cover the same distance. we need to find the speed of the train.

Answers

Let take speed of the train = x km/hAnd time taken by train in normal speed = y hoursA train travels a distance of 480 km at a uniform speed.Distance = speed × timeSo we get x*y = 480 …..(1). If the speed had been 8 km/h less, then it would have taken 3 hours more to cover the same distanceNew speed = x – 8 km/hTime taken = y + 3 hoursUse same formula againDistance = speed × time
